<p>The present invnetion relates to a glenoid prosthesis (100) with a hybrid design (combining both peg and keel designs), for reconstitution of a shoulder joint. The hybrid design combines both peg (25,35) and keel (50) components into one device. The hybrid glenoid component of a shoulder prosthesis includes an oval body (10) having a concave lateral articulating surface (12) and an opposing convex medial surface (11). The medial surface is provided with a plurality of pegs (25, 35) and a single inferior protrusion (50). The pegs (25,35) are used to attain both a superior location as well as a central location. The inferior protrusion (50) provides stability in the superior-to-inferior translation of the humeral head, as well as rotational articulation of the same.</p> |
